  • The purpose of reliability prediction is to estimate the basic reliability and basic reliability and mission reliability of system and to make a determination of whether these reliability requirements can be achieved with the proposed design. Also, potential design weakness can be identified through the FMECA process. This technical memo summarizes the KOMPSAT-2 reliability and FMECA analysis results.

  • Construction industry is a complex industry which should be invested with plenty capital, manpower and resources. Investment factors and inner and outer environmental factors should be managed systemically in terms with risk factors possible to occur. It maximizes the profit to establish construction management by managing risk systemically. While previous studies were executed with risk related to some special progress lively, studies about risk in managing construction company leave much to be desired. Therefore, this study examined risk in the whole construction management, showed the checklist and deduced the quantitative factors through questionnaire analysis from specialists. Also, priority and grade of construction management factors were evaluated by analyzing weight of construction risk factors.
